I have worked for 2. Granted, they're unlikely to be massive, unicorn successes - but they are successes, none the less.
My opinion is largely the era of the unicorn is essentially gone. Except for extremely rare moonshots (like OpenAI), markets just don't simply have many multi-billions of value for a disruptive startup.
I believe tailscale is remote only. Personally remote doesn’t work for me, I feel my motivation and mental health go into a tailspin after a while, but there is no denying some companies have made it work.
